Question

1.5 L of water at 100°C
is placed in a large aluminum pot with a circular base of radius
15cm and a thickness of 0.40cm. The pot is then placed on a stove
burner that is delivering heat to the outside bottom surface of the
pan as shown in the diagram below. The temperature of the outside
bottom surface of the pan that is directly in contact with the
stove burner is 102°C.
Assume that thermal conduction of heat energy only occurs through
the bottom of the pan and that the coefficient of thermal
conduction for aluminum is kAl=240 W/mK.
